'To all whom it may concern:

Be it known that I, EnnBon, citizen of the Unitedstates, and a resident of Clear-V brook, county of Clearwater, State of Min-f nesota, have invented a new and useful Improvement in Knives, of which the following is a full, clear, and exact description.

This invention relates to knives and has particular reference to a pocket, or socalled ae-n knife in which the cutting blade or blades thereof are adapted to assume an open or closed position relative to the handle in which they are mounted.

The primary object of the invention is to provide a novel means for locking the blade or blades in either an open or closed position relative to the handle.

A further object of the invention is to do away with the customary springs which are usually embodied in the construction of knives of this type, thus providing a knife which aside from the many advantages of the locking feature for the blade or blades,-

will wear longer than the ordinary knife, to represent a more staple structure, and an improvement in many other ways over what has heretofore been accomplished.

With these and minor obectsin View the invention will be' more readily understood upon reference to the accompanying drawing in which,

Figure l is a top planview of one embodiment of the invention.

Fig. 2 is a side elevation.

Fig. 3 is alongitudinal section showing the blade partly closed, and

Fig. 4 is a longitudinal section showing the blade as locked in open positionin full lines, and in closed position in dotted lines.

Referring to the drawing in detail it will of course be appreciated from the following description that the knife may be made of various sizes and designswitheither a single or plurality of blades, without departing from the spirit of the invention. Ac

cording to the illustration'shown in the drawing the'knife is constructed with the customary handle 5, the sides of which being spaced apart provide a recess or elongated slot in which is pivoted the blade 6. The

pivotal mounting for the blade is prefer ably arranged in one end of the handle at the end of the recess therein and comprises the pin 7 Specification of Letters Patent:

.55, adapted; to be swung about its pivot to open I reasons to lock the blade in either an open 7 or closed position the pivoted end of the blade is constructed with the shoulder 8 in one of its edges, with the opposite edge ofiering a substantially fiat surface. Longii tudina-lly' presented in the recess of the handle and pivoted therein intermediate. its ends,as at 9, is a lever 10, which extends substantially the length of the recess. One

end of the lever ispresented adjacent the pivoted end of'the blade, with the opposite end presented adjacent a cam disk 11 with a portion of which it is adapted to have a wiping] contact r-so that-the cam may rock theleveraboutits pivot to present the end ad acent the plvoted end of the blade in the shoulder 8 when theblade 6 is in open position, whereupon it may be thus locked in this position. To maintain the engagement, the cam is provided with a stop or abutment 1%, which bears against the end of the lever adjacent the cam, thus preventing any thrust on the blade disen a ing the end b t: of the lever from the shoulder 8.

When it is desirable to close the blade, the

cam disk 11 is turned contra-clockwise about j locking engagement with the blade and the its pivot, whereupon the lever is raised from blade is free to be swung about its pivot to closed position. When the blade is closed the'cam disk is turned clock wise about its pivot, whereupon it will again effect awiping contact with the lever, thus causing the blade engaging end thereof to bear against the fiatsurface "on the pivoted end of the blade opposite theshoulder; and so long as the abutment 12 on the cam disk which extends beyond the handle engages the adjja-" cent end of thelever, the lever will resist an effort to open the'blade by swinging the same about its'pivot. i

The portion of the edge of the cam disk is serrated to offer a roughened surface in order'that the disk may be easily manipulated.

' As stated the invention is in no way confinedto a single blade knife asits advantages may be realized in connection with a J plurality of blades in. which instance the blades may be selectively used, with those blades not in use locked in closed position,

with the blade in use locked in open position and when none of the blades are in use all ofthem may be collectively lockedin closed position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows A knife comprising a handle, a blade pivoted in the handle and adapted to assume an open or closed position and be locked in said; positions, a lever pivoted intermediate its ends within the handle and constituting the back thereof, one end ofsaid lever having a flat stepped portion, the pivot end of the blade having on one side a shoulder, and a flat portion extending from said shoulder to that end of the blade and on the opposite side the blade having a continuous fiat portion whieh'with the shouldered side, 'ooact with the' aforesaid'fiat stepped portion of the back lever, a" locking cam pivotally inner end rounded and adapted to have wip ing contact with the adjacent end of the back lever, andits outer end projecting beyond the end of the handle and having a serrated rounding edge, terminat ng ;1n

stop shoulder adapted to; abut the adjacent end of the back lever to lock the blade in complete open or closed position, 'substantially as herein shown and described;
